Addition Recovery
Targeted practice to strengthen addition skills from basics to multi-digit.
Path Steps
Addition within 10
Start hereReinforce basic addition facts.
Why the path starts here
Recovery starts below the point where the child is stuck. Sums to 10 should feel easy; if they do not, every later step leans on finger counting, so this is the place to find out quickly.
Sets up: Addition within 20
Skills in this step
- Add numbers with sums up to 10
- Learn ways to make 10
- Use all 10 fingers for counting
4 + 4 = ?
- Start at 4 on the number line.
- Count forward 4 steps.
- You land on 8.
Answer: 8
Addition within 20
Build fluency with sums to 20.
Why this step comes next
Sums to 20 cross the ten for the first time (8 + 5). A child who makes 10 on the way gets these right without counting on, and that fluency is what two-digit addition needs.
Sets up: Adding Two-Digit Numbers
Skills in this step
- Add numbers to get sums from 11 to 15
- Use making 10 strategy for teen numbers
- Understand that 11 = 10 + 1, 12 = 10 + 2, etc.
6 + 6 = ?
- 6 needs 4 more to make 10.
- Split 6 into 4 and 2.
- 6 + 4 = 10.
- 10 + 2 = 12.
Answer: 12
Adding Two-Digit Numbers
Practice adding without regrouping.
Why this step comes next
Two-digit addition without regrouping adds the ones, then the tens, as two small facts from the steps before. Keeping each column under 10 isolates the place-value idea before carrying is added.
Sets up: Addition with Regrouping
Skills in this step
- Add tens to tens
- Add ones to ones
- Combine for the answer
76 + 13 = ?
- Break apart both numbers by place value.
- 76 = 70 + 6
- 13 = 10 + 3
- Add the tens: 70 + 10 = 80
- Add the ones: 6 + 3 = 9
- Combine: 80 + 9 = 89
Answer: 89
Addition with Regrouping
Master regrouping (carrying) in addition.
Why this step comes next
Regrouping is the one new idea here: when the ones add up to 10 or more, ten of them become one ten. It comes after the no-regrouping step so that the carry is the only thing that can go wrong.
Sets up: Multi-Digit Addition
Skills in this step
- Recognize when regrouping is needed
- Regroup 10 ones as 1 ten
- Complete addition with regrouping
17 + 63 = ?
- Break apart both numbers by place value.
- 17 = 10 + 7
- 63 = 60 + 3
- Add the tens: 10 + 60 = 70
- Add the ones: 7 + 3 = 10
- 10 ones = 1 ten and 0 ones (regrouping)
- Combine: 70 + 10 = 80
Answer: 80
Multi-Digit Addition
Add three-digit numbers confidently.
Why this step comes next
Three-digit addition repeats the same column method with one more column, and regrouping can now happen in the tens as well. A child secure on the previous step is extending a method she already has.
Skills in this step
- Add hundreds, tens, and ones
- Line up numbers correctly
- Work from right to left
673 + 113 = ?
- Line up the numbers by place value.
- Add each column from right to left.
- Ones: 3 + 3 = 6
- Tens: 7 + 1 = 8
- Hundreds: 6 + 1 = 7
- The answer is 786.
Answer: 786
